In version 0.9.0 the catalogs are just loaded into RAM, and if you do not have enough of it, swapping will start. Add up the star catalog sizes, compare with your amount of RAM, and your common sense will tell you how many files you can load. Yours, Johannes

In Stellarium version 0.9.0, star catalogues are split into 9 files, which contain stars of varying brightness. These files can be found in the <installation directory>/stars/default/. Only the smaller four of these files come with Stellarium in the main package to keep the size manageable.

About 99% of all these stars come from the NOMAD catalog (Naval Observatory Merged Astrometric Dataset version 1, by USNO). The rest (brighter ones) from Tycho2 and Hipparcos. Please see the stellarium README file for the conditions, under which you may redistribute data files originating from NOMAD.

Here is a list of all available catalogues. The RAM needed column is an estimate. (MNG managed to load file 7 with 512 M ram, but only just. YMMV).
